How to change DEUI (device ID) on I-NUCLEO-LRWAN1 ?

Hello,

I'm using a I-NUCLEO-LRWAN1 shield plugged on a NUCLEO L073RZ board. I'm trying to make the I-CUBE-LRWAN AT-master example run on the Nucleo L073rz. As documentation explain i opened SB13 and SB14 and closed SB62 and SB63, i also redirected the stlink to the uart4 with flying wire to be able to program the board.

To connect to my LoRa server i need to change my DEUI but the shield return an error "ERROR_INVALID_ARGUMENTS" (which is not even in the documentation of the software package) when i try to change it with the AT+EUI=XXXXXXXXXXXXXXXXX command.

Does anyone have any idea on why we can't change the DEUI?

According to the USI LoRa manual AT+EUI is a READ-ONLY command, so you're not going to be able to change it.
